UNITED STATES Application serve its intended purposes, and yet the roll,

A roll embodying the invention is shown in the accompanying drawings. Fig. I is a view of the roll partly in side elevation, partly in axial section; Fig. 11 is a view in end elevation.

The roll includes a shell of impervious material, ordinarily of metal, faced with felt. To hollow cylindrical roll body 1, the

heads 2 are one or both of them adjustably secured, as by the screw-thread connection 10. The space within constitutes an in reservoir. The heads 2 are of greater diameter than the body 1, and they present opposite faces 20 between which opposite felt, advantageously built of 3, encircling the body 1, is by the application of and'adjustment of the removable head or heads, securely clamped. 1 is perforate, that the ink within the reservoir may while the roll continues in service have access automatically to the felt face of the roll. This body of felt soaks up theink so supplied to it. Its consistency 15 is thus available on its to meet the service. The preparation of the ink ink having prop-pr physical characteristics are matters wit u the knowledge of those who use such apparatus.

Throughout so much of the extent of the cylinder as may be desired, and as here shown throughout the imperforate portion of the cylinder, to the other side of that axial plane, superficial grooves 31 extend.' These grooves ext-end transversely and are here advantageously shown to extend semicircumfer entially, from one perforation O to another, and they preferably exfind helically upon the cylindrical surface.

3 throughout half its cylindrical extent imperforate, it is adapted when in proper position to contain without escape and without consequent seepage through the ,felt, a body of ink which fills the reservoir less than half full. By virtue of the fact that the body 3 throughout this half of its exthe ink issuing when the roll is in rotation through perforations 30 is distributed beneath the felt roll body and the whole of the felt facing plied with ink.

A filling hole closed by a removable plug 21 may be formed at a convenient place; here it is shown to be formed in one head 0 the cylinder. cation, such as the arrow 22 or the line 23 And the head may bear indior both, that the user may know when the roll is in position .with the perforations 30 all above the the grooves horizontal axial plane, and with 31 entirely beneath the horizontal axial plane. We have said entirely above and entirely beneath-the axial plane, whereas Fig. 11 of the drawings shows the extreme perforations 30 centered in-a diameter of the cylinder, so that, accurately the diameter of one perforation, the perforate area exceeds a half cylinder. But the purportand meaning of the description will, with'allowance for this, be understood It will be perceived that the head which bears these indiciami ht be integral with or'otherwise positively xed in its position relatively but if-it be united to screw-thread engagement. as shown, when screwed to-position upon body 1, the

The roll is for all purposes of operation maintained on a horizontal axis. The filling hole is preferably drilled through the head in such position that when the assembly is completed it shall lie on the-same side of the cylinder with perforations and on the This relative assembly has so been made plug 21 maybe removed and through the hole ink may be introduced into the reservoir. within, in quantity to fill the reservoir not more than half full. The plug 21 may then be replaced. The roll may then be rotated and used and ink will be supplied through the felt facing after the usual manner'.

We claim as our invention:

An inking roll consisting of a cylindrical body of impervious material provided with a superficial facing of pervious material, the cylindrical body to one side of an axial plane affording an imperforate semi-cylindrical ink trough, the cylindrical body in such portion being provided on its outer surface with transversely extending grooves, and the cylindrical body to the other side of such axial planebeing provided with ink conducting perforations.

In testimony whereof we have hereunto set our hands.
